A pear falls off of a bowl's edge with a "Plop." "Zoom" is the sound a plane makes as it flies into the sky. A cat—watching a ball go by—utters a single "Meow." This brightly colored board book of sounds (and makers of sounds)—full of pop art graphics with dotted backgrounds à la Roy Lichtenstein—will make language development fun for young prereaders (and readers will have fun voicing the sounds that rubber duckies, speeding cars, and drippy faucets make).
